clasification of iron ore

Metallurgy Matters: Carbon content, steel classifications

The carbon content of cast iron is 2.1 percent or more. There are four basic types of cast iron: Gray cast iron , which is relatively soft. It's easily machined and welded, and you'll find it used for engine cylinder blocks, pipe, and machine tool structures. White cast iron, which is hard, brittle, and not weldable. It has a compressive ...

Chemistry for Kids: Elements - Iron

Iron occurs naturally in the form of four stable isotopes: 54 Fe, 56 Fe, 57 Fe, and 58 Fe. Around 92% of iron is 56 Fe. Oxidation States Iron can exist in oxidation states from -2 to +6. The most common states are +2 and +3. Interesting Facts about Iron. Cast iron is when an iron alloy is heated to liquid and then is poured into a mould.

Iron Ore - an overview | ScienceDirect Topics

Mining iron ore or other iron-bearing materials from the ground is the first step to make iron and steel. Iron ores are rocks from which metallic iron can be economically extracted. These rocks are usually found in the form of hematite (Fe 2 O 3 ) or magnetite (Fe 3 O 4 ).

The Complete Classification of Minerals

The iron group contains iron (Fe) and nickel (Ni). These metals possess a body-centered cubic structure. Nickel and iron are mutually soluble because their atomic radii are both equal to 1.24 angstrom. This solid solution is frequently found in meteorites and probably constitutes much of the earth's core.

Geological ore deposits - The Australian Museum

The iron and manganese ores occur as distinct sedimentary layers alternating with iron and manganese-poor sedimentary layers - the whole mass is sometimes mined. Iron ores of this type are commonly termed the banded iron formation or simply abbreviated as BIF. All ore minerals in these deposits are oxides and hydroxides.
